One 'onclick' for two events/actions.

draig_hand

Hello all,
I have an image on my productspage.php that when clicked presents a WinZip.exe file for the user to run or save.
I also want that same click to send me an email , unknown to the person downloading the file, that tells me "Product X Downloaded"
I do not need the senders email details!
I have tried to find a solution though googling but can find nothing.
I have a php script that sends me such an email when the page is opened but cannot see how to combine this with the download action.
